' y s claim. (c1. irs-29s) duce an electric lighter of the type described in vwhich the resistance is shielded so as to prevent breakage of the resistance wire and to prevent undue cooling of the resistance wire by drafts. It is also possible by my invention to use thisshield to protect the flaming wick from drafts as Well as to protect the resistance wire.

Another object of my invention is to produce an electric lighter wherein the wick-carrying element can be entirely detached from the source of "current used to heat the resistance wire. More particularly my invention relates to a manner of combining in one independent unit thewick, the

reservoir for feeding the wick, and the resistance wire.

An additional object of my invention is to provide a readily replaceable resistance unit for electrical lighters of the type described.

Still another object is to provide a resistance wire which is capable of being heated to a strong heat and which is not corroded by the volatile liquids used to supply the wick.

Further, my invention is designed to produce a simple, inexpensive and efiicient lighter structure of the type described. To this end the batteries and connections used are made to effect the maximum economy of space and material.

Other objects and advantages will be apparent from the following description taken in connection with the appended claims and the accompanying drawings, in which:

Fig. 13 is a circuit diagram of part of my device.

In the drawings, 2 indicates what I term the torch unit. This unit comprises a tubular casing i of electrical conducting material. This tube has 5 an annular shoulder 8 near one end for a purpose to be described below. The portion 'I between the shoulder 6 and the end of the tube 4 is used as a handle to manipulate the torch. This same end of the tube is closed by a screw-threaded plug 8. 10

The other end of the tube 4 is closed by a wall I0 having an opening I2 therein vand having a stepped portion I l adjacent the opening. 'Through the opening I2 a wick I3 extends to the interior of the unit, the wick being surround- 15 ed by cotton I 6 or other absorbent packing. This packing is adapted to hold any usual type of volatile lighter uid which may be supplied by removing the plug 8.

In the stepped portion I4 of the end wall of 20 the torch unit a block of insulation I8 is slidably tted. This block of insulation has mounted e thereina short post 20 of conducting material and a longer post 22 also of conducting material. Between these' posts is secured a line resistance 25 wire 24', preferably made of a nickel-chromium alloy. A nickel-chromium wire is capable of being heated to a strong heat.- It has also been found that this alloy resists corrosion by volatile liquids ofthe type ordinarily used as a fuel for the wick.

The tubular portion 4 of the torch unit is extended as at 26 beyond the end wall I0 on the side adjacent the resistance unit. This extension partially surrounds the resistance unit and the. posts 35 which support the resistance wire. It is to be noted that the longer post 22 extends beyond the end of this shielding extension. This shield also protects the llame on the wick from drafts and' partially shields the eyes of the user from the name.

In order to securel the resistance unit to the torch unit a single screw 28 is used. This screw extends through the wall of the torch unit and through the insulation block I8, making contact 45 with the short post 20 as at lill. By this simple expedient the short post is electrically connected to the casing of the torch unit and the resistance unit is secured in place upon the torch. To replace the resistance u nit all that is necessary is 50 to remove the screw 28 and pull out the unit which includes the two posts,` the resistance wire and the block. This unit may then be replaced by another unit of like construction.

When not in use the torch unit is adapted to 55 be housed within the casing 32 which may also contain the source oi' electric energy used in heating the resistance unit'. This housing may take the i'orm of a metallic tube I4, closed'by the wall 38 at one end. The shoulder 8 on the torch unit prevents this removable unit from being inserted too far into the housing tube. At the same time. this shoulder, due to the weight oi the torch unit, will seal the exposed end of the wick from the atmosphere when.the torch is placed within `the housing..

The source of electric` energy preferably is housed within the metallic casing 32 which also includes the housing tube for the torch unit. This metallic casing has a top wall 40 and a bottom wall 42 electrically connected through the medium of side walls 44 and the torch housing tube. The parts are fixed together by the screw 48 which holds the housing tube to the bottom wall and by the shoulder 48 on the outer end of the housing tube which engages the top wall 40.

The top wall contains sheets of insulation B0. At one point the top wall is provided with an aperture 52 through which a contact piece 54 extends. This contact piece is insulated from the top wall by means oithe insulating

vpieces

58 and 58, being bent around the piece I6. These insulating pieces hold the contact piece in position and are held in place by wedging the sides oi' piece I6 into the aperture 52.

The bottom wall of the container is provided with

apertures

80, 62 and 84. 'I'hese apertures are provided so that dry cell batteries 86, $8 and 10 can be easily inserted in the container.

Fig.,13 shows diagrammatically the connections between the batteries, the contact piece and the casing. As shown, the contact piece is in direct connection with one end of the battery i8. The other end of this battery is connectedy by means of the spring strip 12 to the bottom of battery 68. The top of this second battery is connected .to the top of the other battery 1liv by conducting strip 14, the bottom of this last battery being connected to the casing through the spring strip 18.

'I'he strips contacting the bottoms oi the batteries may be conveniently located by mounting the same on a rigid sheet of insulation 18 which is secured to the bottom wall oi' the container by means of the screw 80. This insulation piece has secured thereto the spring strips 12'and 16 previously noted. The spring strip 1B is positioned to extend from a point adjacent the center of the end of battery 10 to contact with the screw 48 which holds the parts of the casing together. 'I'he strip 12 connects the batteries 6B and 68 when the piece 18 is in position.

The other connection between the batteries is made through the strip 14 which is positioned in the top of thev casing below the insulation 50.

'This strip 14 is carried by a strip oi. insulating material 82, the ends of the strip 14 being bent around the ends of the insulation 82 as at 84 and 86. These ends contact the batteries 6l and 10 when the batteries are inserted in place. The insulating strip is held in place by the side walls of the container.

When it is desired to use the device for igniting a cigarette or cigar the torch unit is withdrawn from the housing, the shield 26 is placed against the top wall of the casing and the post 22 is pushed into contact with the contact piece $4. Electric conduction will then be established as follows:

Starting with the contact piece I4 the circuit Awill flow through the battery il, the, spring strip 12, the battery Il, the strip 14, the battery 10, the spring strip 1i, the screw 4l, the casing 32 including the top' wall 4I, the shield 20, the screw 28, the post 20, the resistance wire 24, the 5 post 22 and contact I4.

'I'he resistance wire will soon become heated to a suiilcient degree to ignite the wick. The unit is then withdrawn from the casing and contact piece and the flame from the wick is l0 used to ignite a cigarette or cigar. It is to be noted that when the wick has been ignited and the unit withdrawn, the resistance unit is no longer heated. It should also be noted that the shield 28, besides shielding the resistance wire l5 and the wick, is used to establish contact in. bringing the resistance unit to igniting heat.

After the torch has been used it is extinguished by replacing it in the tube 34, the shoulder l cutting of! air for combustion and preventing 20 evaporation of the lighter iluid.

Attention is called to the i'act that the

batteries

66 and 10 are in upright position while the battery 68 is in an inverted position. When the batteries are thus arranged the proper connec- 86 tions are assured.
